Recently, we took a deep dive into some data about Super Bowl TV sales from last year. In that data, provided by market research firm Gap Intelligence, we discovered that the two weeks leading up to the Super Bowl were indeed the best time to purchase a new TV. The data also showed that HDR TVs were nearly twice as expensive as non-HDR ones, online prices were actually higher than those in-stores, and Westinghouse had the best prices on-average for TVs between 50" and 70".

But, like we alluded to in that previous analysis, Gap provided up with a trove of information that we were still attempting to dig through. And dig we did.

Below you'll find a more focused analysis on the TV market over the four years that Gap has recorded such data. For this report, we looked closer at TVs in the 60-inch to 69-inch size range—the sweet spot for a consumer looking to buy a large screen TV—and we broke it down in a number of different ways.

Among some of the more interesting findings:

TV prices are very-clearly trending down, when you remove the HDR sets. Consumers aren't quite ready for HDR, and neither is the industry from a content-ready perspective, so we removed HDR TVs from the picture when analyzing the overall average price of TVs in this size range. The average price hit a low of $1,387.80 during the week leading up to Super Bowl 50 last year.

The trend of retail stores having lower-priced TVs than the online outlets wasn't a one-time thing. And the data here proved that our earlier analysis wasn't skewed by the inclusion of a wide range of screen sizes. For all four years that Gap Intelligence has recorded data, 60-69 inch TVs were priced lower (on average) in store as opposed to online.

Looking at the HDR vs. non-HDR TVs, our previous analysis really told you all there is to know. And that's because HDR technology really didn't come onto the scene until last year. There was no record of an HDR-enabled TV in the 60-69 inch range in 2013 or 2014, and last year there were only 10 TVs available that had HDR. In 2016, though, that number skyrocketed to nearly 1,400 TVs.

Many thanks, again, to Gap Intelligence for opening up their data to us. We've had a blast going through it and will continue to do so for some time.
